Unable to use jquery in nodejs

Question

I am newbie to Javascript/jquery. I am writing a simple js file that parses a csv file.

var jquery = require('jquery');

jquery.get('file.csv', function(data) {
   alert(data); // this is a line
   var tempArray = data.split(','); // array of data
   for(var i = 0; i < tempArray.length; i++)
   {
       console.log(tempArray[i]); // probably index 1 is your IPv6 address.
   }
});

When I run the code above, I get the following error:

jquery.get('file.csv', function(data) {
       ^

TypeError: jquery.get is not a function
    at Object.<anonymous> (/Users/ishabir1/Desktop/transloc/parser.js:3:8)
    at Module._compile (module.js:410:26)
    at Object.Module._extensions..js (module.js:417:10)

    at startup (node.js:136:18)

Can someone please advise? Thanks!

Dude, try not to use client side libraries on server-side. They will mess things up. Node has various modules to play with file system and parsing data, where fs in a core module. — Nivesh

@Nivesh you're right. I was confusing the client vs server side frameworks. Thanks! — robinhood91

You cannot use jQuery like that in the Node.js realm.

You need to rely on the fs module for reading files, and on a csv library for actually parsing your data, see example:

var fs = require('fs');
var parse = require('csv').parse;

var parser = parse(function(err, data){
  console.log(data);
});

fs.createReadStream('file.csv').pipe(parser);

Don't forget to run npm install csv before requiring it!

what does this line do: var parse = require('..');

I npm installed csv, and now I get the error that parse is not a function.

See edit again, I took the example from the csv-parsesubmodule.

Thank you, it does work now! Is this the best way to parse a csv file in a nodejs application?

If you want to be a Jedi in csv parsing kindly refer to node-csv and there Github repo
